Comfort and Convenience
Cabin temperature divides people more than almost anything else. One person feels a warm car as comfortable, another finds the same air stifling, so a setting that suits the driver often needs adjusting for a passenger.
Safety and Driver Assistance
Before setting off, it helps to adjust the mirrors and seat and to locate the hazard switch. These are small preparations, but they belong to the stationary minutes rather than to a moving car.
Multimedia and Connectivity
Hands-free calling is a distinct need from music or charging. Where a car supports it, a call can be answered without holding a phone; where it does not, the sensible choice is to let it ring.
